Application April 15, 1948, Serial No. 21,111

jThis invention consists of anvimproved toilet seat and means or adevice which has for its object three main purposes; 1) for facilitationof theA excretion of the waste from the human system; (2) for the savingof toilet paper; and (3) for sanitation.

An object is to provide an improved toilet seat which is simplificationof the device and structure shown and described in my prior applicationfor patent on Toilet Seat, Serial No. 19,272, .filed April 6, 1948, andmore particularly with reference to the means for causing movable orslidable sections interposed in opposite sides ofthe seat, to benormally held in, in alignment with respect to the widths of said sides,and to slide .or shift outwardly under the weight of a person reposed onthe seat in use, to cause the thighs and buttocks to be spread,separated or pulled apart and the area surrounding the rectum to bestretched when excreting fecal material, to facilitate and easeexcretion of waste material so as to maintain said area or parts as wellas the seat and bowl in clean and sanitary condition by reason ofconfining the excretion and saving on the use and expense of toiletpaper.

Another object is to provide a toilet seat with slidable sections at thesides, adapted to move in and out on inclined planes, means beingprovided Ato normally cause the sections to move upwardly and inwardlyon said planes to positions in alignment with the sides of the seat whenthe latter is not in use and said sections adapted to move outwardly andforwardly with respect to each side of the person using the seat to pullapart, spread or separate the thighs and buttocks and stretch the areasurrounding the rectum thereby facilitating excretion of waste materialand preventing contact ofthe fecal material with parts surrounding therectum to retain the same clean and save toilet paper.

with the above and otherobjects in view, my Y 5 Claims. (Cl. li-2,37)`

Referring to the drawings, I0 designates a toilet seat of conventionalcharacter and any suitable durable material, having the bight portion II attached at the back edge to a closet 4bowl in any desired manner, andprovided witharcuate sides I2 terminating in spaced forward ends I3, sothat the seat as shown'is of substantially horseshoe shape. The sides I2of the seat I0 intermediately or at the points of greatest lateralcurvature or projection are provided each with a transverse forwardlyangled slot or recess I4 in its upper portion so that the two slotsdiverge forwardly in obtuse angled relation to each other to receivesimilarly related oppositely inwardly and outwardly slidable or movabletop plates or sections I5 each provided with roughened, crisscross orcorrugated top surfaces I6 so that surface friction with the thighs andbuttocks of a person reposed or sitting on` and using the seat, isincreased.

The front and rear ends of the slots, recesses or grooves I4 and thecorresponding coacting and intertting ends of the sections I5 at eachside,

are'parallel and extend diagonally entirely across the sides I2 from theinner edges to points adjacent or short of the outer edges thereofforwardly from the inside to the outside and said sections conform tothe curvature, shape and plan of the portions of the sides I2 determinedby the ends of the slots I4 and are concave on the inner edges andconvex on the outer edges the same as sides I2.

rIhe slots I4 extend entirely across the thicknesses of sides I2 whichas with the entire top face or surface of the seat Ill are generallyconvex as indicated at I6 and flat and on a horizontal plane at thebottom face or surface as at II including the base or bottom portionsbelow slots incline generally outwardly, the longitudinal bottom innerportions or top surfaces I9 thereof for the lengths of the slots of lessthan half the width of the slots and seat sides, sloping from a pointsubstantially intermediately of its height or thickness but preferablyslightly below the halfway point being inclined downwardly toward theoutside but terminating short of the trans-I verse center or less thanhalf the wdthof the sides I2 or cross section thereof and terminating ina shallow or short vertical wall or surface forming an inwardly facingshoulder 29. From this point, the bottom of the slot I4 or top surfaceof the bottom wall thickness formed by the 5 slot, is inclined or slopedin an opposite direction or inwardly as at 2l, being elevated toward theoutside and terminating in such direction by a similar but shallowershort vertical wall or surface formingfl a second outer .inwardly`facing 10 shoulder 22 still slightly inwardly ofthe transverse centersof the sides I2 but medially to a vertical outer wall or surface 23formed by a". vertical cut-out or recess 24 in the sides I2 at .the`outer ends of the slots I4. The top surfaces`25" 15 from walls orsurfaces forming inwardly facing..- shoulders 22, incline or slopeoutwardly,to.outwardly facing vertical walls 23, iniinclinedplanesparallel to the inclined planes of the innerportions or surfaces I9 butoppositely at the oppositesidesIZ of theseat l0.

The sections I5. are similarly formed to. oppose thebottom portions-ofsides I2 of .reduced .thickness where said sides are .provided with theslots I4, .that'is,v the :bottom portionsconstitute the. lower halfportions or.. thicknesses. of thewall. portions ofithe sides I2 at.the.slotsl-.l4.integral with thef'remaining.portionsr'of the.seat,fw.hile. the plates orsectionsl 5fconstitute the upperhalf.portions orthicknesses of the wallpcrtions of. the sidesI2.at.theslots:l4 therein.

4 parted from sections I5 or otherwise formed and attached thereto inany suitable manner as by screws 36.

Slidable sections I5 have pairs of inclined parallel end ribs 31slidable in guideways or grooves 38 in the vertical Walls of slots I4 inwhich sections I5 are loosely received and move with a sliding fit,Anti-friction means are provided between sections I5 and the bottomportions of sides I2'formedby slots, recesses or 'grooves I4, and morevparticularly between inclined surfaces I9 and 26, and 25 and 30,respectively. As shown, spaced parallel anti-friction cylinders orrollers 39.--are\ journaled at their ends or shafts in and carried bysection I5 at semi-circular grooves llinsurfaces 26 to roll onsurfaces'IS, or vice versa, andsimilarspaced parallel cylinders orrollers` 4I` are" journaled at the bottom walls formedby. slots I4, insemi-circular grooves 42 in surfaces 25, to roll againstsurfaces 30 oron which thelatter move, or vice versa.

In this way, sections l5 at opposite sides I2 -of the seat lareadaptedtomove out and'down the inclines, and in andup same, in oppositedirections. However, sections I5 are normally held .in and up or inraised positions alignedwith sides I2 as by any number of springs 43.having their ends seated` inisockets or countersinks or'counterbores 44to retain the springs in position toy normally move the sectionsinwardly, upwardly and rearwardlyand raise themin their guidewaysA orsliding mounts to positions inalignment'with sides I2 at slots I4.

Normally, a: person has to excretel the waste from his body twice'dailylandthese operations cause more or less-strain. Thisstrain which isdetrimental and .unfavorable takes .one form or another, for exampleseparating the thighs andv squeezing the stomach, or by pulling apartthe buttocks with the handsrandat thesame time tioned discomforts. seatof horseshoe shape, the buttocks rest on Owing. to the weight of theperson exerted on these sections or plates they will slide outward:because each of these plates rests on inclined planes built in the baseof the seat. The cylindrical rollers facilitate the sliding of platesIor sections.

countersinks 44 are used to bring back the sections or plates as soon asthe Weight is removed"- from it. When a person sits on the seat,automatically the plates move outward and owing to people dirty not therectum but the surrounding area of the rectum when eimretingv fecalmaterial. Therefore; the surroundings stretched by th`e-present'improved toiletv seat, are freed from contacting fecal material, thussaving toilet paper. lThe latter being true also accomplishes the secondpurpose of vthis device. The third purpose of the device, forsanitation, is accomplished vthroughthe elimination of the act ofcleaning the surrounding area of the rectum. This device therefore ishelpful inexcreting' the waste,` very sanitary' and most 'economical.`

Although the seat as shown inthe drawings is round or substantiallyround, the preferred form is substantially oval in shape; therefore, vitwill The springs which are held in position by the two pairs ofv beunderstood that the shape can be either oval or round, but preferablyoval.

Y I do not mean to confine myself to the exact details of constructionherein disclosed but claim all variations falling within the purview ofthe appended claims.

2. An improved toilet seat comprising a body having spaced apart sideportions, an upwardly opening transverse stepped slot formed in the topof each of said side portions, the bottom surface of said slot beinginclined downwardly and outwardly and including intermediate verticalportions, a movable seating section in each of said slots, the lowersurface of each of said sections being complementary to said bottomsurface and inclined downwardly and outwardly for slidable engagementwith said slot bottom surface, resilient means disposed between thevertical portions of each of said slots and the associated movablesection and adapted to constantly urge said section inwardly andupwardly, and means depending from said section adapted to engage saidside portion for limiting the inward movement of said section.

3. An improved toilet seat as set forth in claim 2 wherein the front andrear walls of said slots are formed with elongated grooves thereinextending parallel to said slot bottom surface, and said sectionsinclude flanges on the opposite ends thereof slidably engaging in saidgrooves to prevent removal of said sections from said slots.

4. An improved toilet seat as set forth in claim 2, whereinanti-friction means are disposed between said section bottom surface andsaid slot bottom surface.

5. An improved toilet seat comprising a body having spaced apart sideportions, a transverse upwardly opening slot formed in each of said sideportions, a movable section disposed in said slot, said slot and saidsection being formed with stepped outwardly and downwardly inclinedslidably confronting bottom surfaces, the steps of said bottom surfacesbeing adapted to abut each other for limiting the outward motion of saidsection, spring means interposed between said steps for constantlyurging said section inwardly and upwardly, and means depending from saidsection and adapted to engage said side portion for limiting the inwardmotion of said section.
